Subject [jira] Commented: (PIG-161) Rework physical plan
Date Thu, 15 May 2008 19:52:55 GMT

    [ https://issues.apache.org/jira/browse/PIG-161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12597240#action_12597240
] 

Alan Gates commented on PIG-161:
--------------------------------

One issue with POCast.  Rather than assuming that it can cast directory from ByteArray to
whatever type, it should be calling the load function that was used to acquire the data, as
we don't necessarily know how to convert bytearray data into a given type (that is, we can't
assume we can call toString on it and then go from there).  That means that POCast will need
to know the load function used to load the data it's casting.

Everything else looks good.  I stripped out the cast stuff and committed the map lookup stuff.
 So when you resubmit the patch you just need POCast and its unit tests.
